Greenback repair

Hi everyone,

I have 4 '69 greenbacks from a matching late 60s 4x12 cabinet.One of them has a small tear about 1.5-2 inches starting from the outer edge of the cone,with no material missing.Can that be fixed without reconing (assuming it's original tone/appearance would be preserved)?

Thanks in advance

You should be able to repair that with paper towel and glue. A hell of a lot of speakers have been repaired like that.

I would think if you took that to a speaker or amp repair tech, they would fix that quickly and cheaply.

Re: Greenback repair

So reconing isn't really a option for such a small tear?

Hey mate

When I read your post I thought you were trying to avoid reconing. I presume to preserve the vintage quality of the speakers??

Re coning is defiantly an option. I have an old 72 vibrolux and the speakers were rooted from dust, and I got them reconed and they sound great. The recone kits are cheap and there are some good ones. One thing I do not know, someone here probarbly does....is how different it would sound. I would assume that old speakers have a certain sound, and I do not know how much of a difference it would make. I am guessing once you have worn it in a bit the difference would be negligible.

Me personally, I would get it repaired and recone only if you have to.

Re: Greenback repair

I can't speak from experience, but I'd try the paper towel and glue first if you can find more details about how to do that. If it doesn't work out, you aren't out anything and you can go ahead with the recone.

Re: Greenback repair

i'd probably use maybe a few layers of tissue paper rather than a paper towel..and a glue diluted with water mix maybe...kinda like paper mache?

Re: Greenback repair

I would like to know how to do this as well. A guy I know has a Vintage 30 with a tear in it for $20. Repairing anything ourselves is better than taking a trip to any shop.

My speaker repair friend told me about it, but I have seen it on Kendricks DVD on tube amp repair and maintenance.

I've used Finger Nail polish and silicone sealer to fix a tear, don't know about paper towel and never heard of that fix but if it works..........

Re: Greenback repair

That's an easy repair,
but DON'T USE WATER.
Water is a speakers worst enemy,
so keep your speakers as dry as possible.

Re: Greenback repair

Hi.

I've used anything from aluminium tape to silicone sealers and if the tear doesn't extend to the surround, almost anything that seals the tear works.
